The G430 earpieces have been designed to be slimmer and lighter, without skimping on audio quality. A lighter, balanced assembly means you stay focused on the game. You might even forget you're wearing a headset. You can hear up to seven discrete channels of audio data plus the low-frequency effects (LFE) channel, known as 7.1 surround sound. Dolby Headphone technology perceptually positions each channel in the correct location to reproduce multi-channel content the way developers intended.
